The street furniture is configured to continuously monitor the AED and ensure it is functional, using a device such as has been described hereinabove. If the AED is used, an ambulance is deployed to the location. The AED that is retained in the compartment may be a smart carry case. As such, the presence, function, and location of the AED can be continuously monitored.

RELATED APPLICATION (PRIORITY CLAIM)

This application claims the benefit of U.S. Provisional Application Ser. No. 62/719,024, filed Aug. 16, 2018, which is hereby incorporated herein by reference in its entirety.

BACKGROUND

The present invention generally relates to methods and systems for providing access to medical devices, and more specifically relates to a portable monitored Automated External Defibrillator (AED) system.

Sudden cardiac arrest occurs when victims have an abnormal heart rhythm called ventricular fibrillation. In this state, the heart cannot beat in a coordinated fashion and blood does not circulate to the heart and the brain. The victim loses consciousness, collapses and appears lifeless. Ventricular fibrillation is a treatable arrhythmic condition. Electrical energy is present in the heart, but is chaotic. The treatment for most cases of sudden cardiac arrest is treatment with a defibrillator to shock the heart out of a fatal rhythm, allowing a normal, healthy rhythm to resume. Although AED's are safe, effective and easily applied, few victims of sudden cardiac arrest have ready access to AED's.

The shorter the time from collapse to defibrillation, the better the chances of survival. If defibrillation is applied within 1-2 minutes, survival rates of 90% have been reported. If defibrillation is applied after 6 minutes, the survival rate is about 45%. Where defibrillation is delayed by more than 10 minutes, the survival rate drops to less than 5%.

Although most victims of sudden cardiac arrest are middle-aged or elderly, many victims are in their thirties. Cardiac arrest may occur at any location, for example at home, in shopping centres, on public transport or at work. Consequently, the widespread availability of AED's at workplaces and in the broader community would be beneficial in addressing the problem of sudden cardiac arrest. There is a need for the widespread provision of AED's to improve the chances of victims surviving sudden cardiac arrest.

In addition to the requirement for widespread provision of AED's, there is also a requirement to ensure that the AED's that are distributed are safe and reliable. The potential for liability associated with AED ownership may limit the ability to achieve widespread provision of AED's. The annual number of AED's distributed between 1996 and 2005 increased almost ten-fold. During that period, the U.S. Food and Drug Administration (FDA) issued 52 advisories involving either AEDs or critical AED accessories. FDA data showed that during this 10-year period, many AED's were recalled due to the potential to malfunction.

The components of a standard AED 50 are shown in the block diagram of FIG. 1. The AED 50 includes electrodes 51 that, in use, are applied to a patient. The AED 50 is a portable device that is powered by battery 53. The operation of the AED 50 is controlled by electronic circuitry 52. A watchdog unit 54 monitors the status of the AED 50. If faults are detected by the watchdog unit 54, an audible alarm indicator 55 is activated to emit an audible alarm.

Some AED's are GPS-enabled. FIG. 2 shows a schematic block diagram of a GPS-enabled AED 60. The three principal components of a GPS-enabled AED 60 are a standard AED 50, a GPS device 61 and a two-way communicator 62. The components 50, 61 and 62 may be standard devices. The combination of the AED 50 and the GPS device 61 permits tracking of the location of the AED, and may facilitate recovery in the event of theft, or assist in the accurate dispatch of a rescuer or ambulance. The two-way communicator 62 may provide communication between the user and, for example, rescuers or ambulance personnel. The GPS-enabled AED 60 is typically a wall-mounted unit, and the entire wall-mounted unit must be removed from the wall in order to use the standard AED 50 component of the system. Additionally, once the GPS-enabled AED 60 is removed from the wall, the battery 53 of the AED 50 is forced to power all the functions of the GPS-enabled AED 60. Furthermore, the GPS-enabled AED 60 does not include any first aid supplies despite the fact that certain first aid supplies might be very helpful to have at the scene at which the GPS-enabled AED 60 is being used.

While this invention may be susceptible to embodiment in different forms, there are shown in the drawings and will be described herein in detail, specific embodiments with the understanding that the present disclosure is to be considered an exemplification of the principles of the invention, and is not intended to limit the invention to that as illustrated.

FIG. 3 is a perspective view of a smart carry case 100 that is in accordance with an embodiment of the present invention. The smart carry case 100 is preferably durable, waterproof, and has high visibility.

FIG. 4 is an exploded perspective view showing internal components of the smart carry case 100 shown in FIG. 3. As shown, preferably the internal contents include a conventional AED 50 which is disposed on one side, inside the smart carry case 100, and a formed insert 102 which is disposed on the other side, inside the smart carry case. The formed insert 102 is preferably configured to keep organized first aid supplies 104 such as scissors, razor, swabs and gloves, a mask, etc. which a user can use in connection with using the conventional AED 50.

Preferably, a mobile AED monitoring and alerting device 110 is disposed under the formed insert 102, out of view from the user, which functions to continuously monitor the presence, function, and location of the AED 50. The device 110 renders the smart carry case 100 a portable GPS-enabled, AED monitoring system that is capable of monitoring an AED 50 and reporting back the presence, function and location of the AED to a remote host 112 (See FIG. 6). As will be described, the device 110 also continuously monitors certain things about itself as well, and reports back to a remote host 112 (see FIG. 6) and/or emits an audible alarm.

FIG. 5 is a schematic block diagram of the mobile AED monitoring and alerting device 110. The device 110 preferably includes one or more GPS devices 114 that permit tracking of the location of the device 110, and includes structure which allows the device to send and receive signals to and from a remote host 112 (see FIG. 6). That structure may comprise a 3G module 116 and associated SIM 118 as well as an antenna 120, such as an external dipole antenna, for communication with a cellular network 122 (see FIG. 6). The device 110 may include dual SIMs 118 to enable communication with two different networks (i.e., as a backup).

The device 110 may also include an audio detector 124 (i.e., microphone and associated processor) which continuously listens for sounds and alarms being emitted from the AED 50 (via the audible alarm indicator 55 shown in FIG. 1), at least one accelerometer 126 for detecting movement of the device 110 (i.e., detecting movement of the smart carry case 100 as a whole), and a speaker or buzzer 128 for emitting an audible alarm.

The device 110 includes a controller 130 (such as a microcontroller unit (MCU)) for controlling the overall functions of the device 110. To that end, the controller 130 is effectively connected to the other components of the device.

The device 110 preferably includes a battery 132 (such as a lithium ion battery) which powers the device, as well as an associated charger and socket 134 for charging the battery 132 using either a wall socket or a vehicle's power system.

The device 110 may also include one or more inputs 138 for effectively tethering the device 110 to something such that removal causes the controller 130 to determine that the device 110 has been disconnected. At that point, the remote host 112 (see FIG. 6) can be notified and/or the device 110 may emit an audible alarm using the speaker or buzzer 128. The device may include an audio vent 140 so the sound emitted by the internal buzzer 128 can be better heard.

With regard to what is communicated back to the remote host 112 (see FIG. 6), these communications can include the fact that the smart carry case 100 is low on battery 132, the battery 132 will not hold a charge, the smart carry case 100 has received an impact or its axis has changed (effectively detected by the accelerometer 126), a fault relating to the AED 50 has been detected (i.e., by the audio detector 124 by effectively hearing fault signals emitted by the AED 50), etc. The device 110 can also be configured such that any or all of these conditions also cause the buzzer 128 to emit an audio alarm.

As shown in FIG. 5, the device 110 also preferably includes external memory 141 to enable remote software updates, and an SMA antenna 143 (i.e., for sending or receiving electromagnetic waves that improves the signal required for remote communications).

As shown in FIG. 6, the smart carry case 100 preferably exists in a network 149 of identical smart carry cases 100 wherein each smart carry case 100 can communicate with a remote host 112 via one or more networks 122 (such as cellular networks). While three smart carry cases 100 are shown in FIG. 6, of course many more can be included in the network 149 as symbolized by the dots 142.

FIG. 7 is a perspective view of street furniture 150 that is in accordance with another embodiment of the present invention, while FIG. 8 is a schematic block diagram thereof which shows some of the main components. The street furniture 150 is configured to retain, continuously monitor, and dispense an AED 50 and communicate to a remote host (i.e., a control room).

As shown in FIG. 9, the street furniture 150 preferably exists in a network 152 of identical street furniture 150 wherein each piece of street furniture 150 can communicate with a remote host 154 (such as control room) via one or more networks 156 (such as cellular networks). While three pieces of street furniture 150 are shown in FIG. 9, of course many more can be included in the network 152 as symbolized by the dots 158.

As shown in FIGS. 7 and 8, the street furniture 150 may include, among other components, a remotely lockable/unlockable compartment 160 (using an electromechanical lock 162 as shown in FIG. 8) for containing and dispensing the AED 50, an intercom panel 164 (i.e., a button 166, at least one speaker 168 and a microphone 170, as shown in FIG. 8), and at least one surveillance camera 172. The street furniture 150 may also include at least one digital display and/or illuminated signage 174, on the front and/or back. As shown in FIG. 8, the street furniture preferably includes a controller 176 which is connected to the components and controls the functions of the street furniture 150, and a two way communicator 178 which functions to enable the street furniture to communicate back and forth with the control room (see FIG. 9).

The street furniture 150 is preferably configured such that a user presses the intercom button 166. In response, the street furniture 150 contacts the control room 154 (see FIG. 9). The control room 154, in turn, sends a signal to the street furniture 150 causing the compartment 160 to unlock (via the electromechanical lock 162 as shown in FIG. 8) so the AED 50 can be removed and used in a rescue. If the AED 50 is used, an ambulance is deployed to the location. The street furniture 150 is configured such that the control room 154 (see FIG. 9) can effectively use the one or more surveillance cameras 172 to monitor activity at the street furniture 150. The AED 50 which is retained in the compartment 160 may be a smart carry case 100 as has been described hereinabove and shown in FIGS. 1-6. As such, the presence, function, and location of the AED 50 can be continuously monitored.

The street furniture 150, and specifically the controller 176 thereof, may be configured to unlock the compartment 160 after a set period of time after the button 166 is pressed, or in the event of power loss. The street furniture 150 may be configured such that this auto-open feature can be deactivated, such as by the control room 154.
